3rd party RS232 and PACA

Hello everyone
I have been looking for a relay solution to control some devices such as garage door opener and AC interface.
It's going to be installed in a data cabinet so 5504RVF is not really suitable due to it's 240V supply terminals.
SPST would be OK but SPDT contacts could be handy.
I found this RS232 relay which seems reasonably priced and hoped to control it with a PAC.

It would need a power supply for the RS232 on the PAC.
After some reading on the forum I am concerned about damaging the PAC and was looking at this isolating device which I think could also provide power for the PAC's RS232 instead of trying to find a 24VAC supply.
Any thoughts appreciated.

So I was hoping someone who has done this before might be able to give a few recommendations.
Or is there a suitable CBus product?
No being much of a programmer I can't quite understand this requirement of the relay though I suspect it would be no problem for the PAC.

And this is how I thought it would look in pascal.

Code:

 OpenSerial(1, 1, 9600, 8, 1, scNoFlowControl, scNoParity);
 WriteSerial(1, '254, 0');

Thanks

 

Have you considered the L5108RELVP? It's bus-powered and can switch up to 30V ac or dc on it's 8 channels. The output contacts are change-over contacts giving lots of flexibility.

Some discussion on it here.

 

Hello Newman
I do remember reading about that product but I couldn't find it on Clipsal web site and I forgot what is was called.
That should do the trick.
Thanks
